The very high X-ray polarisation of accreting black hole IGRJ17091-3624 in the hard state
Melissa Ewing, Maxime Parra, Guglielmo Mastroserio +26
We report the first detection of the X-ray polarisation of the transient black hole X-ray binary IGRJ17091-3624 taken with the Imaging X-ray polarimetry Explorer (IXPE) in March 20…
Constraining gas motion and non-thermal pressure beyond the core of the Abell 2029 galaxy cluster with XRISM
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137
We report a detailed spectroscopic study of the gas dynamics and hydrostatic mass bias of the galaxy cluster Abell 2029, utilizing high-resolution observations from XRISM Resolve.…
Supermassive Black Holes in X-rays: From Standard Accretion to Extreme Transients
Erin Kara, Javier GarcÃa
X-rays are a critical wavelength for understanding supermassive black holes (SMBHs). X-rays probe the inner accretion flow, closest to the event horizon, where gas inspirals, relea…
Frequency-resolved time lags due to X-ray disk reprocessing in AGN
Christos Panagiotou, Iossif Papadakis, Erin Kara +6
Over the last years, a number of broadband reverberation mapping campaigns have been conducted to explore the short-term UV and optical variability of nearby AGN. Despite the exten…
A second-generation URANS model (STRUCT) applied to a Generic Side Mirror and its Impact on Sound Generation
Jorge Munoz-Paniagua, Javier GarcÃa, Eduardo Latorre-Iglesias
A generic side mirror can be approximated to the combination of a half cylinder topped with a quarter of sphere. The flow structure in the wake of the side mirror is highly transie…
